If you have a crashdump, can you print the vm_page_t at 0xc1655fb8,
it's object, the address of kernel_object_store and the vm_object_t
at 0xc075a440 if it's not kernel_object_store.  I've been seeing
these panics with a patched version contigmalloc() and it would be
nice to know if there's a bug outside these patches.
